I think it would be very helpful to the general user-base to have instant intelligent access to their information in a way that is sandboxed from the website that is requesting information. The only thing keeping me using chrome is the intelligent autofill. Many websites do not autofill. This issue is also present on firefox for android. Single sign on applications have difficulties on android as well when using mozilla password manager, as it does not get its secure "unlocked" status from the android system. This results in needing to unlock the password manager on the keyboard every time, often making the user lose the text field they had their cursor on.
